Turn your desk into a towering, cathedral-packed mega-city—the kind that stretches for miles, where billions live under spires, battlements, and endless industry. This 3D printable pen holder is inspired by that unmistakable grimdark hive-world aesthetic: gothic arches, fortified walls, clustered spires, and baroque city-block density… all wrapped into a functional desktop organizer.

It’s basically a mini fortress-city for your pens—perfect for anyone who loves dark sci-fi, monumental architecture, and the vibe of a planet that’s been “under siege” for the last ten thousand years.
